As a covenant system to keep for right standing, no. Christ fulfilled the law and you are no longer under it. But its heart, love for God and others, is now written on your heart by the Spirit and lived out from the inside, not imposed from the outside.
The Grace Answer
This sounds like a trick question, and the answer surprises people on both sides. As a covenant system you keep in order to stay right with God, no, Christians are not under the Ten Commandments. Paul could not be clearer: you are not under law but under grace, and we have been delivered from the law, having died to what we were held by.
That is not a license for chaos, and it does not mean the moral vision of the commandments evaporated. It means the whole arrangement changed. Under the old covenant, the law was an external code that demanded obedience and condemned failure. Under the new, God writes His own heart onto yours and produces the life from within.
Fulfilled, not erased
Jesus said He did not come to abolish the law but to fulfill it, and He did. Every demand it made, He met. Now, Paul says, love does no harm to a neighbor; therefore love is the fulfillment of the law. The believer led by the Spirit does not need a stone tablet forbidding murder and theft, because love for God and neighbor already covers and exceeds all of it. Nine of the ten commandments reappear in the New Testament as descriptions of Spirit-led life, not as a code to earn standing. The one that does not is the Sabbath, which the New Testament treats as fulfilled in Christ our rest.
This is what people miss when they fear that leaving the law means chaos. Grace does not lower the standard; it raises it and then supplies the power to meet it. The law said do not murder. Jesus reached past the act to the hatred behind it, then gave you a new heart that can actually love the person you once resented. So the difference is the engine, not the destination. The law drove behavior by demand and fear. Grace produces it by love and new life. A Christian is not trying to keep ten rules to stay accepted. A Christian is already accepted and finds the heart of those commands flowing out naturally.
Live from the Spirit, not the stone. You will not fall into lawlessness. You will find you fulfill the law’s deepest intent without ever living under its weight.
